Subject: [RFC v1 00/19] Add unified Intel Ethernet RDMA driver (irdma)
From: "Saleem, Shiraz" <shiraz.saleem@...el.com>
This patchset adds a unified Intel Ethernet RDMA driver that
supports a new network device E810 (iWARP and RoCEv2 capable)
and the existing X722 iWARP device. The driver architecture
provides the extensibility for future generations of Intel HW
supporting RDMA.
The underlying LAN driver for X722 ("i40e") and E810 ("ice")
have their own peer/client interface that this unified RDMA
driver registers to. The netdev_priv structure of each LAN
driver accessed by the netdev_priv() interface exposes their
peer register/unregister function pointers for use by the RDMA
driver. This solution revives an earlier submission [1] intended for
a different purpose. It now serves to unify the RDMA driver and
we are requesting feedback.
The unified driver is currently being tested on X722 with rdma-core-v22.
X722 is supported by this driver, but only if CONFIG_INFINIBAND_I40IW
is disabled in the kernel. We desire to deprecate or phase out i40iw
from the kernel and can submit patches to do the same. We would like to
move forward with this unified driver model for current and future HW.
This series was built against rdma-next.
commit 21a428a019c9 ("RDMA: Handle PD allocations by IB/core")
It includes both net and rdma patches for the purposes
of review. It will be split into two separate patch series, one for
net-next and rdma-next once RFC is accepted.
